Stellar Atmospheric Parameters of M-type Stars from LAMOST DR8

Ming-Yi Ding, Jian-Rong Shi, Yue Wu +9

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data of M-type stars, and the derive…

Lithium Evolution of Giant Stars Observed by LAMOST and Kepler

Jinghua Zhang, Jian-Rong Shi, Hong-Liang Yan +8

Mapping lithium evolution for evolved stars will provide restrictions and constraints on the fundamental stellar interior physical processes, which further shed light on our unders…

Chemical abundances of three new Ba stars from the Keck/HIRES spectra

Shuai Liu, Liang Wang, Jian-Rong Shi +4

Based on high resolution, high signal-to-noise (S/N) ratio spectra from Keck/HIRES, we have determined abundances of 20 elements for 18 Ba candidates. The parameter space of these…

The Lithium Abundances from the Large Sky Area Multi-object Fiber Spectroscopic Telescope Medium-resolution Survey. I. The Method

Qi Gao, Jian-Rong Shi, Hong-Liang Yan +9

Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge-up process (FDU). Yet a small fraction of giant stars are still found…

LAMOST/HRS Spectroscopic Analysis of Two New Li-rich Giants

Zeming Zhou, Jianrong Shi, Hongliang Yan +9

Two Li-rich candidates, TYC 1338-1410-1 and TYC 2825-596-1, were observed with the new high-resolution echelle spectrograph, LAMOST/HRS. Based on the high-resolution and high-signa…

Most Lithium-rich Low-mass Evolved Stars Revealed as Red Clump stars by Asteroseismology and Spectroscopy

Hong-Liang Yan, Yu-Tao Zhou, Xianfei Zhang +19

Lithium has confused scientists for decades at almost each scale of the universe. Lithium-rich giants are peculiar stars with lithium abundances over model prediction. A large frac…

Searching for r-process-enhanced stars in the LAMOST Survey I: The Method

Tian-Yi Chen, Jian-Rong Shi, Timothy C. Beers +5

The abundance patterns of -process-enhanced stars contain key information required to constrain the astrophysical site(s) of -process nucleosynthesis, and to deepen our under…

Lithium-rich Giants in LAMOST Survey. I. The Catalog

Qi Gao, Jian-Rong Shi, Hong-Liang Yan +5

Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge up process (FDU). Yet a small fraction of giant stars are still found…

High-resolution spectroscopic analysis of a large sample of Li-rich giants found by LAMOST

Yutao Zhou, Hongliang Yan, Jianrong Shi +6

The discovery of Li-rich giant has cast a new challenge for the standard stellar evolution models, and to resolve this issue, the number of this type object has been rapidly increa…

The nature of the Li enrichment in the most Li-rich giant star

Hong-Liang Yan, Jian-Rong Shi, Yu-Tao Zhou +13

About one percent of giants\upcite{Brown1989} are detected to have anomalously high lithium (Li) abundances in their atmospheres, conflicting directly with the prediction of the st…
